He cried with a loud voice, as a lion roars. When he cried, the seven thunders uttered their voices.

ἑαυτῶν he'autōn “their own”

When the seven thunders sounded, I was about to write; but I heard a voice from the sky saying, "Seal up the things which the seven thunders said, and don't write them."

ἑαυτῶν he'autōn “of themselves”

but in the days of the voice of the seventh angel, when he is about to sound, then the mystery of God is finished, as he declared to his servants, the prophets.

ἑαυτοῦ he'autou “His own”

However much she glorified herself, and grew wanton, so much give her of torment and mourning. For she says in her heart, 'I sit a queen, and am no widow, and will in no way see mourning.'

αὐτὴν autēn “herself”

Let us rejoice and be exceedingly glad, and let us give the glory to him. For the marriage of the Lamb has come, and his wife has made herself ready."
